摘　　要：利用系统结构演化分析的方法,构建竞争系统的择劣竞争模型,以揭示在优先选择低竞争力对手的机制下系统的结构特征与演化性质。解析与模拟结果都表明:在择劣竞争机制驱动下,大量低竞争力节点将会被快速淘汰出竞争系统,长期中系统宏观结构状态呈现出较强的时间无关性和稳定特征;同时也证实不同的微观竞争机制将呈现不同的系统宏观结构特征与演化性质。刻画客观世界中普遍存在的"优胜劣汰"的竞争现象。Using the system architecture analysis method,this paper constructs a reverse preferential competition model of competition system in order to reveal the systemic structural features and evolution nature.Analysis and simulation results show that driven by the reverse preferential competition mechanism,large number of nodes with low competitiveness will be quickly eliminated from competition system,and that long-term existence of the system macro-structure has shown a strong time-independent state and stability structural features.At the same time,this study confirms that different micro-competition mechanisms will show different characteristics of macro-structure and evolution nature of systems.In addition,this study depicts a competition phenomenon of ＂survival of the fittest＂ prevailing in the objective world.
